When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -3c - 3c = -7c + 2x - 7 for c in terms of x.
| 1\(\frac{1}{3}\)x - \(\frac{2}{3}\) | |
| 1\(\frac{1}{7}\)x + \(\frac{6}{7}\) | |
| \(\frac{5}{14}\)x + \(\frac{1}{14}\) | |
| 1\(\frac{1}{4}\)x - 1\(\frac{3}{4}\) |
